Why does this awk script not work correctly?
I have a large database with English on the left hand side and Indic words on the left hand.
It so happens that since the Indic words have been entered by hand, there are duplicates in the entries.
The structure is as under:
Code:
English headword=Indic gloss,Indic gloss

A small sample will explain
Code:
10=दहा
10th=दहावा,दशम
11=अकरा,अकरा,एकादश
11th=अकरावा
12=बारा
12th=बारावा
13=तेरा,तेरा,त्रयोदश
13th=तेरावा
14=चौदा
14th=चौदावा
15=पंधरा
15th=पंधरावा,पंध्रावा
16=सोळा
16th=सोळावा
175=पावणेदोनशे,एकशे पंचाहत्तर
17=सतरा
17th=सतरावा
18=अठरा
18th=अठरावा
190=एकशेनव्वद
19=एकोणीस
19th=एकोणिसावा
1=एक
1st=प्रथम,पहिला
20=वीस
20th=विसावा
21=एकवीस
21st=एकविसावा
22=बावीस
22nd=बाविसावा
23=तेवीस
23rd=तेविसावा
24-hour interval=दिवस
24-karat gold=शुद्ध सोने,खरे सोने,अस्सल सोने,बावनकशी सोने

As can be seen some duplicates in the Indicword are present:
Code:
13=तेरा,तेरा,त्रयोदश
11=अकरा,अकरा,एकादश

I wrote an Awk script to remove such duplicates
Code:
# script to remove dupes from a row with structure word=word
BEGIN{FS="="}
{for(i=1;i<=NF;i++){a[$i]++;}for(i in a){b=b"="i}{sub("=","",b);$0=b;b="";delete a}}1

However when the script runs, it mangles the output file.
What has gone wrong?
Many thanks for your kind help.

Sorry the English is on Lefthand and Indic on right hand separated by
